To Zt lwim/fit t 'may concern:

Be it known that l, CHARLES 'I'. lVns'rLAnn, a citizen of the United States, residing at Louis, Missouri, have invented a certain new and useful Improvement in Locomotive- Tender UnderirameS, oi which the following' is a full, clear, and exact description, such as will. enable others skilled in the art to which it appertains to malte and use the same, reference being had to the accompanying` drawings, forming aart of this speciiication.

My invention relates generally to locomotive tenders, and more particularly to a bed or nnderfraine tor the tender, the principal objects oil? my invention beingto provide a relatively strong, rigid and substantial. nnderirame; to construct the nnderirame in a single piece, preferably by casting` thereby greatly simplifying and minimizing the cost of production and providing a construction which eliminates all joints and connections between assembled parts; to forni. integral with the underiframe various brackets and bearings for parts associated with and carried by the underirame; to i'orm body holsters integral with the nnderi'rame and to construct parts of said body bolsters so that they will have ample strength in resisting certain 'torsional stresses that are produced by the inertia of the truck during hailing and pullingstrains.

lWith the ioregoing and other objects in view, my invention consists in certain novel features et construction and arrangement oit parts, hereinafter more -inlly described and claimed, and illustrated in the accompanying drawings, in which- Figure l is a plan view of a tender 'undert'rame ot my improved construction.

Fig. 2 is a section taken approximately on the line 2-2 of Fig. 1.

Fig. 3 is a side elevational view of the underframe.

Fig. et is an enlarged detail section taken approximately on the line Mii ot' Fig. 1.

Fig. 5 is an enlarged detail section taken approximately on the line 5-5 of Fig. 1.

Fig. 6 is an enlarged section taken approXiInately on the line 6 6 of Fig. 1.

Fig. 7 is an enlarged plan view of a part of one of the side sills of my improved underirame.

Fig. 8 is a cross section taken on the line 8-8 of Fig. 7.

Fig. 9 is an enlarged cross section taken on the line 9 9 of Fig. 1.

As heretofore stated, I propose to form my improved undertrame in a single piece, preferably by casting', and as illustra-ted, said underitrame comprises a pair of side sills 10, a iront end sill 11, a rear end sill 12,y a pair oi'E holsters 13, and a pair of longitudinal center girders lll, the end portions and lo oil which or those portions between the holsters 13 and the end sills 12 and 11 being arranged closer together than the main body portions ol' said girders or those portions between the bolsters. T he nndertrame also includes an integrally formed trans versely disposed member 1T disposed at a peint substantially midway between the holsters 18.

.llie side sills l() may be el any desired cross sectional shape, although l prefer to make these end sillsot Iii-beam shape with the webs vertically disposed. Likewise the main body portions or those portions et' the center girders between the holsters 18 are ot I-beam shape in cross section `with their webs vertically disposed. The rear end sill 12 is preferably hollow and oi: box-lil e structure, and formed integral with its central portion is a rearwardly projecting baiting member 18. The portions 15 ot' the center `wirders are preferably channel-shape in cross section with the webs vertically disposed and the top and bottom flanges outwardly presented, and the space 19 between these end portions is utilized for the draft rigging that is associated with the drawbar positioned at this end or" the undert'rame. .in order to accommodate this draft rigging, the members 15 are extended downwardly a short distance below the plane occupied by the lower portions of the main bodies oit' the center girders 14 and certain lugs and brackets may be formed integral with the inner faces ci. these members 15, and which lugs or brackets cooperate with parts of the dra't't ri gging.

The portions 16 ett the center girders or these portions between the front end sill 11 and adjacent bolster 13 are preferably of I-beam shape in cross section, and termed integral with their forward ends and with the front end sill 11 is a depending housing 2O in which are formed pockets 21 adapted to receive parts of the drawbar and safety bar which connect the tender undertrame with the locomotive underframe.

The end portions of the bolsters 'l1 or those portions between the side sills l() and center girders 14 are preferably of I-beani shape in cross section with the webs verti cally disposed and the central portions of said bolster-s or those portions between the center gil-ders are provided with a pair oit vertically disposed webs 23, thereby provid ing a box-like section. (See Fig. 6).

Formed integral with the webs 23 are Vtop and bottom plates 24 and 25, and which latter, it will be understood are practically continuations of the top and bottom webs on the adjacent portions oi? the holsters and 'tbe center girders.

iecured in any suitable manner to the central portions oi the bottom plates 25 are center liearings 2G which are adapted to cooperate with corresponding" bearings on the bolsters et the truck which support the tenfer vSiamo.

."i locomotive tender under'lframe ot my iininnoved construction combines great strength and lrigidity with minimum weight, and said underiirame can be easily and cheaply produced owing to the tact that it can be readily cast in asingle piece and the elimination of joints `in the nnderframe entirely overcomes structural weaknesses which invariably develop where an assembled or fabricated structure is subjected to service strains and vibrations.

Wvhile in service and particularly during batting and pulling strains the inertia ot the trucks produce torsional stresses in the lower portions ot the body holsters and to counteract and absorb these stresses, the centrai portions of the bolsters of my improved nnderframe are reinforced and strengthened by the transversely disposed parallel webs in such construction being` easily and cheaply produced and very eliective in pei formingl the intended functions.

It will be readily understood that minor changes in the size. form and eonstrnction o'lv the various parts ot my improved loco-- motive tender undcrfranie can be ,made and substituted for those herein shown and dcscribed. without departing' from the spirit of my invention, the scope olf' which is set torth in the appended claims.

I claim:

l. A locomotive tender irame cast in a single piece and comprising a pair oit ilanged side sills. a pair opff box-shape end sills, a pair ot flanged center `girders or sillsT and a pair oi'v tlai'ig'ed holsters, the centeiportions of which l'ioluters are box shaped.

2. A, locomotive tender 'traine cast in one piece and comprising the following; elements `which are integrally connected together: a pair ot flanged side sills, box shaped end sills`r flanged draft and center sills. and 'flanged bolsters, the central portions oi? said bolsters being;r box-shaped and said draft sills having recesses and parts cast integral therewith for the mountingr of the drait lagging.
